Set Up WFS Service on MapServer and display in OpenLayers

Question

I have used following mapfile to create the WFS service on Mapserver but struggling to display the service output using OpenLayers.

Please suggest some links to use WFS service in openlayers.

Thanks in advance.

Answer 1

you can check out this example here for source code - MapServer WFS Demo and OpenLayers 2.10 SLD support for vector styles.

Beside this you can glance at:

• MapServer and OpenLayers configuration here

• WFS: WA National Parks Example, here

and your wfs call for vector layer similir to this:

lyr = new OpenLayers.Layer.Vector("WFS protocol continents", {
        strategies: [new OpenLayers.Strategy.BBOX()],
        protocol: new OpenLayers.Protocol.WFS({
                      "url": url,
                      "propertyNames": propertyNames,
                      "geometryName": "msGeometry",
                      "featureType": "continents",
                      "featurePrefix": "ms",
                      "srsName": "EPSG:4326",
                      "maxFeatures": 1000,
                      "version": "1.0.0"
                  })
    });

i hope it helps you...
